This document discusses three examples of predicted landslide catastrophes in New Zealand and the challenges of communicating risk to decision-makers. In the first example, a potential landslide in Kaikoura could generate a tsunami killing over 100 people. While known since 1999, the risk has not been properly addressed. The second example evaluates risks of landslides in Franz Josef endangering over 100 people, which is unacceptable. The third examines landslide risks at Milford Sound that could kill 400 people and endanger employees, far exceeding acceptable safety standards, yet reducing tourism is politically difficult. The key responsibilities of scientists are to publish comprehensive risk assessments and correct any misrepresentations, holding politicians accountable for ignoring foreseeable disaster risks.
